Well, in the sentence I used above I juxtaposed data with money. Money is the data of human action. But the money to which I am referring has an accounting method that using the signing of messages constructed of addresses, and amounts. The signature itself part of the accounting as well.
So, while it may seem clever to say money is data this is about as relevant as saying a square IS a rectangle. Then when building something specifically designed for shapes longer than they are wide using nothing but squares.
The nuance is obvious if not trying to be obtuse.
